The First US Nuke In 20 Years Goes Online—TVA Project


The Tennessee Valley Authority (TVA) announced that the Watt Bar Unit 2 nuclear generation unit is now online at full power, providing commercial electrical energy.  It is the first new nuclear power generation unit in 20 years.  Good for them. TVA has 6 other Nukes providing power.

TVA president and CEO Bill Johnson said:

“TVA’s mission is to make life better in the Valley by providing reliable, low-cost energy, protecting our area’s natural resources and working to attract business and growth – all priorities simultaneously supported by the completion of Watts Bar Unit 2..”

A Westinghouse pressurized water reactor is expected to generate 1,150 megawatts (summer net capability). The capital cost of the complete generation unit was $4.7 billion.

Small-Scale Renewables Program Failure.


Operation of a small-scale wind farm was undertaken at Lake Land College** about 4 years ago. Now the College is planing to tear down the two wind turbines because of high maintenance cost and the wind farm’s inability to provide the College’s power requirements.

According to a Daily Caller posting, the turbines returned a negative 99.6% return on investment. The posting tells us the  College got  $987,697.20 in taxpayer support for the wind power. The turbines were funded from a $2.5 million grant from the US Department of Labor.

The college has spent $240,000 in parts and labor attempting to keep the wind turbines in operation. But they are now inoperable with an  estimated cost of $100,000 to get them back online.

From the Daily Callers posting:

“School officials’ original estimates found the turbine would save it $44,000 in electricity annually, far more than the $8,500 they actually generated. Under the original optimistic scenario, the turbines would have to last for 22.5 years just to recoup the costs, not accounting for inflation. If viewed as an investment, the turbines had a return of negative 99.14 percent.”

“Even though the college wants to tear down one of the turbines, they are federal assets and “there is a process that has to be followed” according to Allee. (Allee is the Director of Public Relations)

“The turbines became operational in 2012 after a 5-year long building campaign intended to reduce the college’s carbon dioxide (CO2) emissions to fight global warming. Even though the turbines cost almost $1 million, but the college repeatedly claimed they’d save money in the long run.”

But the College nor the US Government are not through with renewable power despite this lesson. According to the Daily Caller posting we learn that they are going solar:

“Lake Land plans to replace the two failed turbines with a solar power system paid for by a government grant. “[T]he photovoltaic panels are expected to save the college between $50,000 and $60,000 this year,”Allee told the DCNF.”

Because the wind farm was planned to be a teaching tool for the College students. It could be that some of maintenance was done be the students. However, maintenance must have been lead by professionals.

Third world countries have vast and legitimate needs for electricity for their people. But the greens tell the third world countries that they do not want to provide them with fossil fuel powered plants. And the World Bank says it will not provide them funding for fossil fuel plant. A study done in a remote part of India found that spreading solar cells around did not work because they needed many trained people distributed through out the area the solar cells were being placed and they just did not have that kind of talent. Enough talent can be concentrated in a power plant. Someday these countries, as they advance, will develop these people but they do not exist now. The people in this part of India, of course did not like loosing power every night, either.

You also wonder who in the Department of Labor determines the appropriateness of these awards. Already having put $2.2million in renewables, they are going for more.

I hope the College knows that they wont have power in the evening. (sarc)

ExxonMobil’s— “The Outlook For Energy-View to 2040″


 

The ExxonMobil Report contains a wealth of information. This posting will look at the status of renewable energy in the context of the world forecasts. While there are a number of postings that contend that renewables will be a dominate player, logic says that will not be true. One recent posting declares that within ten years the world could be supplied exclusively by renewable. I would take that bet on the other side.

First some background from the ExxonMobil Report.

The world population will grow from 7.2 billion in 2014 to 9 billion in 2040. India will replace China as the world’s most populated nation at 1.6 billion people. The globes energy demand will increase by 25% from 2014 to 2040. The report believes without their forecasted improvements in energy use, demand would be double their 2040 forecast shown in the report’s 2040 forecast.

The chart below is their forecast of world energy demand 2014 to 2040:  (click on charts to enlarge)

The Perilous Business Of Predicting The Future


The National Review.com posted “Why Climate Change Won’t Matter in 20 Years”. They subtitled the posting “The perilous business of predicting the future.” The subtitle accurately depicts what happens when politicians or anyone for that matter, think they can safely make the future an extension of the present.

First of all, the warmers should be willing to take seriously the abject failure of their vaunted climate models to make prediction on any time frame. Yet they insist that the Earth in 2100 will be x degrees hotter and the sea level will be y meters higher than today because the climate models told them so. The odds are that they might do just as well talking to Madame Charmaine, the village palm reader.

The author of this posting, Josh Gelernter, put in a lot of effort into showing why projecting the present as a representation of the future is very unlikely to be successful. So I will let him speak:

“Michael Crichton — the brilliant novelist and thinker — posed this horsespulling streetcarquestion in a speech at Caltech in 2003, re climate predictions for 2100. What environmental problems would men in 1900 have predicted for 2000? Where to get enough horses, and what to do with all the manure. “Horse pollution was bad in 1900,” said Crichton. How much worse would someone in 1900 expect it to “be a century later, with so many more people riding horses?”

Study Shows Global Tree Count 7.6X Larger Than Previously Thought.


Nature .com posted a study titled “Mapping tree density at a global scale”. This appalachiansimagesstudy dramatically changes our understanding of the number of trees on the globe. The study’s count is 3.04 trillion trees (3.04X10^12), which replaces the previous estimate of global trees of 400billion (400X10^9). As a point of reference, the study also expresses the change as trees per humans. Considering the currently estimated total global population of 7.2 billion (7.2X10^9), the study now shows the old count of 61 trees per person has grown to 422 trees per person.

New Count Old Count

Did CO2 Cause North Korea’s Environment To Collapse?


Why is North Korea’s environment in a state of collapse? Well it is not due to global warming, global climate change weather weirding or what ever the new evasive title is. From the Public Broadcasting System (PBS) “Nova” program titled “Inside North Korea’s Environmental Collapse” we learn this:

“North Korea has been hiding something. Something beyond its prison camps, its nuclear facilities, its pervasive poverty, its aching famine, its lack of energy—electrical, fossil, or otherwise. What the hermit kingdom has been covering up is perhaps more fundamental than all of those: an environmental collapse so severe it could destabilize the entire country. Or at least, it was hiding it.”

What initiated the collapse? Nova had this to say:

“North Korea’s isolation means detailed data on environmental conditions are hard to come by. However, a 2004 study by the Korea Environment Institute based in Seoul, South Korea, reports that forest cover in North Korea dropped by 17 percent from the 1970s to the late 1990s. Following the collapse of the Soviet Union, which provided oil to its communist ally at a discounted “friendship price,” oil imports dropped by 60 percent. Unsurprisingly, the use of firewood for heating more than doubled.

“What resulted was an increasingly barren landscape. Even saplings are felled for fuel, stripping forests of their ability to regenerate. “They don’t have trees to hold the soil,” says Jinsuk Byun of Sookmyung Women’s University in Seoul. Byun was not a part of the recent delegation but has closely followed environmental conditions in the country. “When it rains the soil washes into the river, landslides occur and rivers flood. It triggers a really serious disaster.”

The Nova program cites loss of wildlife as follows:

” The lack of birds and other small animals noted by the scientists on their recent visit are a direct result of the famine in the 1990s, Demick says. “The frogs disappeared because everyone caught the frogs,” Demick says. “You see many fewer birds and small animals in North Korea than other countries. People living near the sea ate seaweed but that also ran out.”

Energy to heat homes. Energy to provide light . Energy to power the equipment to farm and do other forms of manufacturing.   The supply of fossil fuels is not sufficient to support the North Korean population.  This is a lesson for those who believe the world can manage without the use of fossil fuels.  Someday, perhaps it will, but alternative forms of energy–wind farm, solar cells and biofuels  are not ready for prime time, so be careful for what you wish.

In this case the North Korea leaders, present and past, are just plain crazy—- imposing a dictatorship that controls all aspects of the lives of the people. As the North Koreans are the same people as their cousins in South Korea, one would expect if the government quit regulating every aspect of their lives, they might be able to restore North Korea. Open up the country and spend the countries money on fossil fuels (energy) and stop spending it on nukes.

Can we trust the EPA? Part 2—Particulate Matter, 2.5 Microns Or Smaller


In the previous posting, it was noted that the Supreme Court stopped enforcement of an EPA regulation that reduced emissions of mercury (Hg) from coal-based power plants. In addition to Hg, the regulation was designated to reduce “Air Toxins”. In this case the toxins are particulate matter—2.5microns (PM2.5) or smaller in diameter.   For perspective, how big is a 2.5micron particle? 2.5 microns are equal to 0.00025 centimeters or 0.000099 inches. Yes, you are right, you can’t see them.

The EPA touts a study that says PM2.5 is dangerous, but they wont share all the secretscienceimagesdata with anyone. Thus, no other science body can confirm or deny the studies results. Secret Science. We are told we must take their word for it.

Bjorn Lomborg Says Global Warming Is A Poor Place To Spend $


Bjorn Lomborg, a Danish economist, joins the “consensus” supporting the theory of man-made global warming (AGW), but not catastrophic man-made global warming (CAGW). He is disliked intensely by the wamers but not because he doesn’t believe in CAGW. He gets this lack of love because he believes that the money spent in the name of global warming is largely misspent. He says the money would be better spent to reduce malnutrition, make immunizations available, better education, prevention of AIDs, providing electrical power to reduce air pollution, etc. These beliefs are laid out in the TED talk video below.

This a fascinating talk.  He shows how much improved Earth has become from 1900 to 2013 and projects changes to 2050.

President Obama Likes German Energy Plan That Results In Electrical Prices 2.5X U.S. Prices


President Obama and polemists like Tom Friedman of the New York Times, tout Germany’s green power program as a model to be admired.   Well, I guess so if you like very much higher electricity prices with only a little effect on CO2 ice_age_endingemissions. As readers of this blog know, CO2 emissions are not high on my worry list. Increased electricity prices are worrisome to me, but they don’t seem to trouble Obama and Friedman?
